I need to setup an autoresponder with form to mail, so people receive a confirmation when they submit the form.
Is this possible with Mailer?

Well its not really related to the mailer script.
You should build this logic in server connect steps. Example - send a mail to the user as well with some link, which updates the database etc.

Hi Teodor

Would I setup a separate Send Mail step in the same Server Action for the confirmation to the user submitting the form?

I suppose one could use the same Send Mail step and send the form results to the user with the CC or BCC in the Extended Recipient panel.
Form results are sent using an HTML file template.

As an expert in email marketing automation, I recommend integrating an autoresponder with a form-to-mail feature for streamlined communication. This setup ensures prompt responses to inquiries while capturing valuable leads.
